CScrollView in the Dialog

I try to draw in the Dialog, but the area, in which I may draw (such as line, rectangels..) exceed the border of the dialog.
So I try to add some controls which may work as the CScrollView, but I don't know how.
I have tried to let the CScrollView as the basic class of the dialog, but then the VC changed the Dialog to the ChildWindow and it effected the other Active Controls.
If somebody has the solution, please tell me ASAP, thanks!

If possible, try to use CFormView for your dialog box.
CFormView is derived from CScrollView.
